To all whom it may concern:

Be it knownthat GEORGE No'r'r, engineer, a subject of the King of Great Britain and Ireland, residing at Vincent Works, Picton Place, Swansea, Glamorganshire, England, has invented certain new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification.

This invention relates to acetylene gas generators in which the carbide chamber is submerged in or located belowthe water level of a water tank or receptacle from which water is fed to the carbide through a tube usually arranged vertically in the centre of the carbide chamber, or through an aperture or apertures in the side of the chamber, the feed being controlled by the gas pressure in the said chamber.

It has been found that with generators of this type uniform production of gas with accompanying steady and constant flow direct from the generator to the burner is only attainable when the water inlet to the car bide is suitably restricted. Hitherto practical considerations have prevented the inlet 1 aperture being made as small as it should be to obtain. the best results, the-difliculty 1 being that a small aperture readily clogs up so that the supply of water to the carbide is rendered uncertain or is liable to stop entirely after the apparatus has been for a short time in use.

Now this invention has for its object to enable the feed water inlet to be restricted to any desired extent for the purpose aforethat it is reciprocated by the movements of the float as the water level varies in the tank under the influence of the gas pressure.

The invention is hereinafter described with reference to the accompanying drawing in which Fig. 1 is a sectional elevation of an acetylene gas generator in which the water inlet to the carbide is provided with a clearing rod in accordance with this invention and Figs. 2 and 3- are similar views to Fig. 1 showing modified constructions of clearing devices. I

The generator shown in Fig. 1 comprises therein andhaving a central water feed tube 0 extending upwards into the chamber, and

a gas outlet tube d extending from the top of thechamber b and communicating with. the burner. Through the feed tube a which terminates in a contracted feed aperture 0 the clearing rod orpin e is arranged to pass and is carried on afloat f located in a water space provided in the feed tank directly below the carbide chamber 6 which has 'a" raised bottom 6 At its upper end the rod 0 may be bent as shown or provided with a suitable head to prevent. its withdrawaltfrgm the aperture in the top of thev feed In this form of generator the carbide chamber 6- is shown closed at the top by a removable cover secured in position by pivot bolts andwing nuts b an india rubber or other suitable washer being interposed between thecover and carbide chamber to form a tight joint. I

When the feed is effected through an aperture in the side ofthe carbide chamber which is possible when the usualsealing bell "so I g isemployed as illustrated in Fig. 2, the I clearing rods or pins for the feed apertures could be operated by-a single float.

In this case, the carbide chamber 6 is open at the top and closed'by the usual sealing bell i from the top of which the gas is conveyed by a pipe d It will be readily understood that the ar-' rangement of the clearing rod andfloat may be varied.

. .On reference toFig. 3 it will be seen that the float f may be on the surface of the water above the carbide chamber bin which event it could be connected to the clearing rod '6 by suitable meanssuch as rod k and lever Z to impart the necessary motion to the rod; I I

By the action of the moving rod or pin e as described the feed water tube ciskept clear and the'feed aperture 0 can be so proportioned that the production of gas without abnormal fluctuations is ensured. Generators of the type described canfbe manently open inlet being subjected to the pressure of the gas in the carbide receptacle, whereby the feed of Water is controlled, and means for automatically reciprocating said rod to keep the inlet opening clear, said means being operated by the variations in the level of the Water in the tank under the influence of the gas pressure, substantially as described. I

In testimony whereof he has afiixed his signature.
